ELEVATOR.

Specification of Letters Patent.

Patented Aug. 2, 1910.

Application filed. January 28, 1910. Serial No. 540,609.

invented new and useful Improvements in Elevators, of which thefollowing is a specification.

This invention relates to elevators, and one of its ob ects is toprovide an lmproved safety door or closure adapted to be operatedautomatically by the car in its upward and downward movement.

Still further objects of the invention are to simplify and improve thegeneral construction and operation of a device of the character outlinedabove.

With these and other ends in view, which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention, may be resorted to when desired.

In the drawings,Figure 1 is a front elevation, partly in section,showing a part of an elevator shaft and a car movable therein. Fig. 2 isa vertical sectional view taken on the plane indicated by the line 2-2in Fig. 1. Fig. 3 is a view in front elevation of the car detached. Fig.4 is a sectional view taken through a portion of the elevator shaft,looking in a forward direction toward the safety door or closure. Fig. 5is a sectional detail view to illustrate the construction and operationof the door-operating mechanism.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The car C is suspended for vertical movement in the shaft by thehoisting element 4, one end of which is connected with a cross bar 10engaging loops or keepers 11 upon the head blocks 12 which extend acrossthe car adjacent to the sides of the latter, the said head blocks beingfirmly bolted or otherwise secured upon the upper ends of the cornerposts 7 of the car.

The door openings at the landings of the elevator shaft are protected bydoors or closures, each of which is composed of two slidably supportedmembers 13 and 14, the upper members 13 being connected with the lowermembers by flexible elements 15 guided over pulleys 16 so that when theupper members are moved upwardly, the lower members will drop bygravity. The upper door members 13 are provided with Weights l7 so thatthey will overbalance the lower door members 14, thus keeping the doorsnormally closed, as will be seen in Fig. 1 of the drawings.

The door members 13 and 14 are provided with resilient engaging membersconsisting of hooks 18 and 19, said hooks or engaging members beingdisposed out of registry with each other, as clearly seen in Fig. 1,said engaging members being secured upon the inner sides of therespective door members which are provided with recesses 20, as shown inFig. 5, for the accommodation of said engaging members. The latterconsists of resilient hooks having beveled engaging shoulders 18 and 19,best seen in Fig. 2, said engaging shoulders being presented in thedirection of the meeting edges of the door members, and the recesses 20being shaped to accommodate the normally projecting ends of the engagingmembers having the shoulders. The front side of the car is providedadjacent to its upper and lower ends with contact members consisting ofloops or plates 20 and 21, best seen in Figs. 2 and 3, the upper contactmember 20 being disposed in the path of the engaging members 18 of theupper door members 13, while the contact members 21 at the lower end ofthe car are disposed in the path of the engaging members 19 of the lowerdoor members 14.

hen, in operation, the car ascends, the contact member 20 will, when thecar approaches a landing, strike the beveled shoulder 18 of theresilient engaging member 18 of the upper door member 13, thus pushingsaid door member in an upward direction, thereby permitting the lowerdoor member to drop by gravity until the floor of the car reaches thelanding, thus uncovering the door opening. When the car ascends beyond apredetermined point, the pressure of the contact member 20 against thebevel shoulder of the engaging member will force the latter to recedewithin the recess 20,

thus permitting the car to pass, the resilient engaging members 19 ofthe lower door member lat being likewise forced back into theirrespective recesses by contact with the members 21, thus permitting theupper door members to descend by gravity and to elevate the lower doormembers until they meet, thus closing the door opening as the carpasses. The operation is reversed when the car descends, the doors beingin this instance moved to an open position by con tact of the members 21with the members 19.

As will be seen from the foregoing description, an elevator is providedwhich is simple in construction and perfectly safe in operation,approach to the elevator shaft being barred by doors which closeautomatically by gravity, as herein described.

Having thus described the invention, what is claimed as new, is

In an elevator, a door comprising vertically movable upper and lowermembers, a suitably guided connecting element, whereby upward movementof the upper door member will allow the lower door member to move in adownward direction, said upper and lower door members being providedupon their inner faces with recesses, and resilient engaging memberssecured adjacent to said recesses and having beveled engaging shouldersfacing in the direction of the meeting edges of the door members andcapable of movement within the recesses, said engaging members upon theupper and lower door members being disposed out of alinement; incombination with a car provided adjacent to its upper and lower endswith contact members disposed for en gagement, respectively, with theengaging members of the upper and lower door members.

In testimony whereof I affix my signature in presence of two witnesses.
